Description

TECHNICAL BACKGROUND

Universal Plug and Play (uPnP) systems allow users to conveniently install and interface numerous data processing products. A user may plug various uPnP devices into a power source and allow the user devices to discover and automatically interface with one another. For example, the user may plug media servers and media clients into their Local Area Network (LAN) and allow the media servers and clients to find each other and exchange media inventory, requests, and content. The Digital Living Network Alliance (DLNA) certifies various user media devices as complying with their uPnP specifications.
Content Delivery Networks (CDNs) also transfer media content, such as video, audio, graphics, and data objects for delivery to various end-user devices. In many content-delivery architectures, two CDNs are used - one for the content source and another for the content destination. These two CDNs exchange data to dynamically distribute media content from source to destination. The data interactions between CDNs are directed by Content Delivery Network Interface (CDNI) standards. CDNI specifies operations like control, logging, prepositioning, inventory, and footprint discovery. The footprint discovery uses Footprint and Capabilities Interface (FCI) data that describes the IP address ranges served by the CDNs.
Some CDNs use wireless communication networks to deliver their media content to user devices like televisions, computers, and phones. Many of these wireless networks have enhanced Multimedia Broadcast Multicast Service (eMBMS) systems to wirelessly multicast high-consumption media content. The CDNs may use these wireless network eMBMS systems to deliver their media content. Unfortunately, wireless communication networks and CDNs do not interface with user devices and their associated uPnP systems in an efficient and effective manner. In particular, the CDNs and eMBMS systems do not effectively interact with user wireless devices and media servers that have uPnP media capability.
EP 2 744 168 discloses live content distribution optimization over a content delivery network, including multicast distribution of TV content. An entity within the network acts as a proxy for a live streaming request, and acts as a server from the end user's point of view. A live streaming optimizer (LISTO) server in a transport network of the content delivery network requests the live media content to a network end point, and transmits the content to a user. A mediator provides information about the requested live media content to the LISTO server, including the network end point, so that an instructor can send back that information to the LISTO server (the instructor having access to information regarding the topology of the content delivery network). US 2012/246480 discloses a method for using a first device to control transfer of encrypted media content from a content provider to a second device, the first device having a security association with the communications network.

TECHNICAL OVERVIEW

A data network receives data associating media content identifiers with a content network identifier and a content user identifier. A wireless network receives a registration indicating the content network identifier and the content user identifier and transfers the content network identifier and the content user identifier to the data network. The data network identifies the media content identifiers associated with the content network identifier and the content user identifier and transfers the media content identifiers to the wireless communication network. The wireless network receives a media request from a wireless communication device indicating the content network identifier and the content user identifier. The wireless network transfers the media content identifiers associated with content network identifier and the content user identifier to the wireless communication device.

DETAILED DESCRIPTION

Figures 1-2 illustrate communication system 100 to transfer media content identifiers to wireless communication device 140. Referring to Figure 1, communication system 100 comprises data distribution network 120, wireless communication network 130, and wireless communication device 140. Data distribution network 120 comprises modems, routers, gateways, servers, communication controllers and databases, and/or some other content-delivery network elements. Wireless communication network 130 comprises wireless base stations, routers, gateways, media controllers and databases, mobility management systems, multicast coordination systems, and/or some other communication network elements. Wireless communication device 140 comprises a phone, computer, media player, or some other apparatus having radio and data capability.
Data distribution network 120 and wireless communication network 130 communicate over data communication links that use IP, CDNI, and/or some other data protocol. Wireless communication network 130 and wireless communication device 140 communicate over wireless communication links that use LTE, Wireless Fidelity (Wifi), and/or some other wireless protocol. These wireless communication links use the wireless protocols (LTE, Wifi, other) to transport the data protocols (IP, CDNI, other). Data distribution network 120 and wireless communication network 130 typically communicate with many other systems over various communication interfaces including the Internet. These communication links and interfaces may be direct or may comprise various intermediate devices, systems, and networks.
Communication system 100 stores, associates, and transfers various data including content network identifiers (IDs), content user IDs, media content IDs, and media content. The media content comprises video, audio, graphics, data files, data objects, and/or some other block of data. The media content IDs comprise uniform resource IDs, data object IDs, data addresses, storage locations, or some other suitable code. The content network IDs comprise data strings that identify individual content delivery networks within a larger content-delivery infrastructure. The content delivery networks may be small or large and include media servers, controllers, and the like. The content user IDs identify individual consumers of the media content and comprise device numbers, account codes, user names, and the like.
In a first operation (#1), data distribution system 120 receives, associates, and stores content inventory data that comprises a content network ID, content user ID, and media content ID. The content inventory data was generated by a user communication system (or proxy) that regularly collects and registers content inventory data with data distribution system 120 over the Internet or some other data communication network.
In a second operation (#2), wireless communication network 130 wirelessly receives user service registration data indicating the same content network ID and the same content user ID received by data distribution network 120. The user service registration data was generated by a user communication system (or proxy) that regularly attaches and communicates over wireless communication network 130. The user communication system that sends the content inventory data to data distribution system 120 may be the same as the user communication system that sends the user service registration data to wireless communication network 130.
In a third operation (#3) and in response to the user service registration, wireless communication network 130 transfer the content network ID and the content user ID to the data distribution network 120.
In a fourth operation (#4), data distribution network 120 receives the content network ID and the content user ID sent from wireless communication network 130. Data distribution network 120 responsively identifies the media content ID based on its association with the same content network ID and the same content user ID in both the content inventory data and the user service registration. Data distribution network 120 transfers the media content ID associated with the content network ID and the content user ID for delivery to wireless communication network 130.
In a fifth operation (#5), wireless communication network 130 wirelessly receives a media request having the content network ID and the content user ID sent from wireless communication device 140. These content IDs may be sent responsive to wireless attachment, application launch, user instruction, or some other trigger.
In a sixth operation (#6), wireless communication network 130 responsively identifies the media content ID based on its association with the same content network ID and the same content user ID in both the media request, the user service registration, and the content inventory data. Wireless communication network 130 transfers the media content ID associated with the content network ID and the content user ID for delivery to wireless communication device 140.
A multitude of additional media content identifiers could be delivered to wireless communication device 140 or other user devices in a similar manner based on numerous content network IDs and content user IDs. As desired, additional layers of security and restricted access to media content identifiers could be implemented.
Referring to Figure 2, the operation of communication system 100 is described. Data distribution network 120 receives content inventory data associating media content identifiers with a content network identifier and a content user identifier (201). Wireless communication network 130 wirelessly receives a user service registration indicating the content network identifier and the content user identifier (202). Wireless communication network 130 responsively transfers the content network identifier and the content user identifier to data distribution network 120 (203).
Data distribution network 120 responsively identifies the media content identifiers associated with the content network identifier and the content user identifier based on the content inventory data (204). Data distribution network 120 transfers the media content identifiers associated with the content network identifier and the content user identifier to wireless communication network 130 (205). Wireless communication network 130 wirelessly receives a media request from wireless communication device 140 indicating the content network identifier and the content user identifier (206). Wireless communication network 130 responsively transfers the media content identifiers associated with content network identifier and the content user identifier to wireless communication device 140 (207).
Advantageously, communication system 100 wirelessly distributes media content identifiers content to user devices in a robust manner based on complex combinations of media content IDs, content network IDs, and content user IDs. As desired, additional layers of security and restricted access to media content identifiers could be implemented.
Figures 3-4 illustrate communication system 300 to transfer media content IDs and media content to wireless communication device 340 through user communication system 310. Communication system 300 is an example of communication system 100, although system 100 may have alternative configurations and operations. Referring to Figure 3, communication system 300 comprises media server 305, user communication system 310, data distribution network 320, wireless communication network 330, and wireless communication device 340.
Media server 305 comprises computer and communications circuitry, memory, and software. Media server 305 and user communication system 310 communicate over a Local Area Network (LAN) or some other communication system. In some examples, media server 305 is a universal plug and play network-attached storage device with media serving logic. Media server 305 stores media content and an associated media content ID, content user ID, and content network ID. Note that media content may be associated with various media content IDs, content user IDs, and content network IDs that are not shown for clarity. Likewise, media server 305 typically stores additional media content that is not shown for clarity.
User communication system 310 comprises computer and communications circuitry, memory, and software. User communication system 310 has a user communication system ID such as an address, serial number, signature, and the like. User communication system 310 and data distribution network 320 communicate over data communication links that use IP, CDNI, and/or some other data protocol. User communication system 310 and wireless communication network 330 communicate over wireless communication links that use LTE, Wireless Fidelity (Wifi), and/or some other wireless protocol to transport the data protocols (IP, CDNI, other). User communication system 310 and wireless communication network 330 may also communicate over data communication links that use IP or some other data protocol. In some examples, user communication system 310 comprises an LTE femtocell.
Wireless communication device 340 has a wireless communication device ID, such as an address, serial number, signature, and the like. Wireless communication network 330 associates the wireless communication device ID for wireless communication device 340 with the user communication system ID for user communication system 310. The association may be based on a multi-device media access plan.
In a first operation (#1), media server 305 transfers the media content ID, content network ID, and content user ID for its current content to user communication system 310. This data transfer may be a push and/or pull and typically occurs on a frequent basis.
In a second operation (#2), user communication system 310 transfers its own user communication device ID along with the media content ID, content network ID, and content user ID to data distribution network 320. Data distribution system 320 receives, associates, and stores content inventory data that comprises the user communication system device ID, content network ID, content user ID, media content ID.
In a third operation (#3), user communication system 310 transfers its own user communication system ID along with the content network ID and content user ID to wireless communication network 330 in a user service registration.
In a fourth (#4) and in response to the user service registration, wireless communication network 330 transfers the user communication system ID, content network ID, and content user ID to the data distribution network 320.
In a fifth operation (#5), data distribution network 320 receives the user communication system ID, content network ID and the content user ID sent from wireless communication network 330. Data distribution network 320 responsively identifies the media content ID based on its association with the same user communication system ID, same content network ID, and same content user ID in both the content inventory data and the user service registration. Data distribution network 320 transfers the media content ID associated with the user communication system ID, content network ID, and content user ID for delivery to wireless communication network 330.
In a sixth operation (#6), wireless communication network 330 wirelessly receives a media request having the wireless communication device ID, content network ID, and content user ID from wireless communication device 340. These IDs may be sent responsive to wireless attachment, application launch, user instruction, or some other trigger.
In a seventh operation (#7), wireless communication network 330 responsively identifies the media content ID based on its association with the same content network ID and the same content user ID in both the media request, the user service registration, and the content inventory data. In addition, wireless communication network 330 enforces security by transferring the media content ID only if the wireless communication device ID from the media request is associated with the user communication ID from the user service registration and the content inventory data. In this example, wireless communication network 330 already associates the wireless communication device ID for device 340 with the user communication ID for system 310, so the media content identifier is transferred by network 330 to wireless communication device 340.
Referring to Figure 4, the third operation (#3) of Figure 3 is updated with user communication system 310 transferring its content-delivery footprint data to wireless communication network 330 in the user service registration. The content-delivery footprint data indicates the IP network addresses served by communication system 330. In some examples, the footprint data indicates the IP address allocations and translations that occur within wireless communication network 330 and user communication device 310. Wireless communication network 330 associates the footprint data with the media content ID based on their common association with the same communication system ID, content network ID, and content user ID.
In an eighth operation (#8), wireless communication device 340 transfers a content request indicating the media content ID to wireless communication network 330. Like the media request, additional layers of data and security could be implemented for the content request.
In a ninth operation (#9), wireless communication network 330 identifies a network address for the media content indicator based on the footprint data associated with the media content indicator. For example, a public network address is identified that will translate through wireless communication network 330 and wireless communication system 310 to transfer the requested media content ID to media server 305. Wireless communication network 330 transfers the media content ID with the network address to user communication system 310.
In an alternative, the ninth operation (#9) is modified where wireless communication network 330 returns a redirect request with the network address for the media content ID to wireless communication device 340. Wireless communication device 340 then retrieves the media content from media server 305 over wireless communication system 330 and user communication system 310 using the network address and the media content ID.
In a tenth operation (#10), user communication system 310 processes the network address using its translations to transfer the media content ID to media server 305. In an eleventh operation (#11), media server 305 transfers the media content to user communication system 310 based on the media content identifier and media request. In a twelfth operation (#12), user communication system 310 transfers the media content to wireless communication network 330 based on the media request. In a thirteenth operation (#13), wireless communication network 330 transfers the media content to wireless communication device 340 responsive to the media request.
Note that additional messaging and CDNI data exchange may occur to facilitate the transfer. Also note that a server ID for media server 305 could be used in a similar manner to the content network IDs in the above examples.
Advantageously, communication system 300 wirelessly distributes media content identifiers and media content to user devices in a robust manner based on complex combinations of footprint data, media content IDs, user communication system IDs, content network IDs, and content user IDs. As desired, additional layers of security and restricted access to media content identifiers could be implemented.
Figure 5-8 illustrate communication system 500 to distribute media Uniform Resource Identifiers (URIs) and associated media content to various user devices. Communication system 500 comprises a Long Term Evolution (LTE) network, Content Delivery Network (CDN), and user equipment. The user equipment includes: a wireless hotspot, Local Area Network (LAN), media servers, media renderers, IP routers/modems, and other user devices.
The media servers and renderers comprise Digital Living Network Alliance (DLNA) systems. The DLNA servers obtain media content from various sources. The DLNA renderers obtain the media content from the DLNA servers for presentation to DLNA users. The user devices are also DNLA capable with controller, server, and/or renderer functionality for the DLNA users. The servers, renderers, and users have associated DLNA server, renderer, and user IDs. Various combinations of DLNA servers form DLNA networks that have DLNA network IDs.
The wireless hotspot comprises LTE/Wifi transceivers, a CDNI controller, DLNA controller, and LAN/IP interface. The LTE network comprises an eNodeB, Multimedia Broadcast Multicast System (MBMS) Gateway (M-GW), and Broadcast Multicast Service Center (BM-SC). The CDN comprises a BM-SC interface, CDNI systems, and DLNA control systems.
Referring to Figure 6, the DLNA controller in the wireless hotspot initially discovers DLNA servers, renderers, and other devices over the LAN and the LTE/Wifi transceivers. The wireless hotspot obtains DLNA data including DLNA network IDs, server IDs, user IDs. The wireless hotspot obtains URIs for media content hosted by the DLNA servers and also obtains additional metadata including media usage and transfer records.
Second, the wireless DLNA controller in the wireless hotspot transfers the DLNA data (network IDs, server IDs, user IDs, URIs, usage/transfer records) to the DLNA systems in the CDN.
Third, the CDNI controller in the wireless hotspot gathers DLNA network, server, and user IDs. The CDNI controller also gathers Footprint and Capabilities Interface (FCI) data for the hotspot including IP allocations and translations in itself and the LTE network, supported CDNI capabilities, and the like. The CDNI controller in the wireless hotspot registers with the BM-SC in the LTE network. The CDNI controller transfers the DLNA IDs and the FCI data to the BM-SC in this eMBMS registration along with the device identifier for the wireless hotspot.
Fourth, the BM-SC transfers the hotspot device identifier, DLNA IDs, and FCI data to the BM-SC interface in the CDN. The CDNI systems in the CDN identify media content URIs for various DLNA networks, servers, and users from its DLNA data based on common associations with the hotspot device IDs and DLNA IDs. The CDNI systems may also process usage and transfer records to identify additional media content URIs to preposition the DLNA networks, servers, and users. The CDN returns the media content URIs for the DLNA networks, servers, and users to the BM-SC.
Fifth, the user device operated by User A transfers a media request to the BM-SC indicating a user device ID, DLNA network ID, and DLNA user ID. This data may be sent responsive to wireless attachment, application launch, user instruction, or some other trigger. The BM-SC identifies media content URIs for User A based on URI association with the common DLNA network ID and DLNA user ID. A layer of security is applied by verifying an LTE network association between the hotspot ID and user device ID. The BM-SC sends the identified media content URIs for User A to the user device operated by User A.
Referring to Figure 7, operations continue after the URI distribution of Figure 6, but the operations are renumbered for clarity. First, the device operated by User A transfers one of the URIs to the BM-SC (or some other LTE system like a gateway). Second, the BM-SC identifies an IP prefix for the URI based on the footprint data that is associated with the hotspot ID that is associated with the DLNA IDs that are associated with the URI. For example, a network address is identified that will translate through the LTE network and the wireless hotspot to the appropriate DLNA network and server. The BM-SC transfers the IP prefix and URI to the CDNI controller and on to the DLNA controller in the wireless hotspot. Third, the DLNA controller in the wireless hotspot transfers the URI to the appropriate DLNA server. The DLNA server returns the media content for the URI to the DLNA controller in the wireless hotspot. Fourth, the CDNI controller in the wireless hotspot transfers the media content for the URI over the LTE network to the device for User A. Additional CDNI request routing data may be exchanged to facilitate this transfer.
Referring to Figure 8, operations continue after the URI distribution of Figure 6, but the operations are renumbered for clarity. First, the device operated by User A transfers one of the URIs to the BM-SC (or some other LTE system like a gateway). Second, the BM-SC identifies an IP prefix for the URI based on the footprint data that is associated with the hotspot ID that is associated with the DLNA IDs that are associated with the URI. For example, a network address is identified that will translate through the LTE network and the wireless hotspot to the appropriate DLNA server. The BM-SC transfers the IP prefix and URI to the device of User A in a redirect request. Third, the device for User A transfers the URI to the DLNA controller in the wireless hotspot through the LTE network, hotspot transceivers, and CDNI controller. Fourth, the DLNA controller in the wireless hotspot transfers the URI to the appropriate DLNA server. The DLNA server returns the media content for the URI to the DLNA controller in the wireless hotspot. Fifth, the CDNI controller in the wireless hotspot transfers the media content for the URI over the LTE network to the device for User A. Additional CDNI request routing data may be exchanged to facilitate this transfer.
Advantageously, communication system 500 wirelessly distributes URIs and associated media content to user devices in a robust manner based on complex combinations of the URIs with IP address translations, Hotspot IDs, DLNA network IDs, DLNA server IDs, and DLNA user IDs. As desired, additional layers of security and restricted access to the URIs could be implemented. For example, wireless network records associating multiple user devices may be used to securely screen requests for the user's CDN URIs. Communication system 500 efficiently associates DLNA data from frequent uPnP device feeds to the CDN with periodic wireless network registration data to associate the CDN URIs for a user with their current wireless communication devices of choice.
